The singer-songwriter started to learn the guitar at age 16 after falling in love with rock music. He formed his first band two years later. He left his hometown Xi'an, Shaanxi province, and came to Beijing, which was considered the base of Chinese rock music, to pursue his dreams in 1994. But no record company was ready to release his works in those early days. So he wrote songs like Birds and Drifting that reflect his struggles.

For one of his early songs, Two Days, released in 1994, Xu wrote: "I have only two days-one for hope and the other for hopelessness."

With a contract signed with Beijing-based indie label Red Star, Xu released his debut album, Elsewhere, in 1997. It helped him stand out from the crowd of aspiring rock singers. He also worked with a range of singers, including Tian Zhen and Faye Wong.

But success didn't come quickly. The market for rock in China, then dominated by pop music, was very gloomy.

Xu didn't hold his first solo concert until he was 37 years old.

On Aug 13, 2005, Xu got his big break with a concert at the Workers' Gymnasium in Beijing, where he performed his hits such as Blue Lotus, Perfect Life and Gift in front of about 10,000 people.

"When the crowds sang along with me, I was amazed," Xu recalls. "It seemed that I had waited for that moment for a long time. I was nervous and thrilled."

But just as his music was beginning to be widely played on the streets and had become popular among people from different walks of life, Xu began to retreat to a slow-paced life. He cut his long hair, quit smoking and was drawn to traditional Chinese culture like tea art, calligraphy and guqin (a plucked seven-stringed zither).

"Music is a cure, which gives me strength and love," Xu says. "The meaning of rock 'n' roll is also different to me. In the past, I wrote songs to relieve emotions like anger and sadness. Now, I see rock as an expression of love."

His days of restless are over, too.

Xu once told a story to his friend, singer-songwriter Ye Pei, that Ye shared on her social media account last week after Xu's live show in Beijing to celebrate his new album. She wrote that one day, Xu noticed a migrant worker singing one of Xu's songs at a Beijing construction site. Xu sat down next to him and listened. Then the singer-songwriter started to sing himself.

"The worker told him, 'You sing just like Xu Wei'," Ye wrote in her post.

"Xu laughed and kept singing."
